Going round clockwise from far left:
Earth and Moon
Mars (wearing stupid bomb-earring; also shades and cigar 'cos he thinks those look hardcore, the twit.)
Sun in the middle (that kerosine lamp can't be good for her head).
Jupiter (I think that blob is meant to be the red spot. Just looks like ketchup from here.)
Saturn
And the other two are either Mercury and Venus or Uranus and Neptune. I don't think they know either.
